I posted a question on the Appliance Pros forum and quickly received responses saying that the problem was likely the flame sensor. I ordered a flame sensor from Appliance Pros and it was delivered in less than 36 hours. I replaced the old part and the dryer is now working fine. This isn't the first time that I received help from Appliance Pros. It's so good to know that there are experts who can help me diagnose appliance problems. I really appreciate it.

I had cleaned the lint out of the dryer exhaust hose, that was usually the problem. But still no heat.
I went online to AppliancePpartPros and watched the videos and was able to diagnose that I needed a new ignitor. .The parts delivered very quickly and I had the job done in 15 minutes. The repair place I called would have taken days to come out just to look at it at..

Previous owner had a short which also affected the terminal block. Instead of capping the two black wires together, they instead ran the bare black to the eye connector and taped together. Poor connection. Subsequently shorted again, cooking the tape to to wires/connector.
Found AppliancePartsPros, as I had ordered previously (simple repair saving me big $$). They had the best price points, correct and quality parts, to include step by step video instructions. I already knew what I needed to do (giving it three stars below for difficulty due to dealing with the electricity) , but I used their video as a teaching tool to spark my nephew's interest/participation. He was apprehensive, but soon was telling me what I needed to do next. Thanks AppliancePartsPros. Will definitely order again if the need arises. I hope not, but if I do....
